基于框支网格式轻质墙板结构抗震性能试验,量化分析结构受力性能,并提出抗震设计建议.洞口侧构造柱的设置弥补了开洞造成的强度衰减,有利于提升墙体的安全储备能力,但加重了墙体后期破坏程度,同时降低其修复能力.斜交肋格的构造形式改变传力途径,使得墙体强度退化趋于均匀,结构具有更好的变形恢复能力,且明显减小墙体的破坏程度,但是整体安全储备能力改善不大.在工程设计方面,建议转换层初始刚度比取值范围大致在1.3~1.6,由于受力过程中结构转换层刚度比衰减较明显,在设计时初始刚度比可适当高些.结构在各个受力阶段的层间位移和层间转角值均在安全界限值以内,进一步说明结构具有较高的抗倒塌能力,耗能减震性能良好.
Based on the seismic performance test of frame-supported lightweight glazing structure, the mechanics performance of the structure is quantitatively analyzed and the seismic design recommendations are put forward. The arrangement of the structural columns at the side of the hole can make up for the strength decay caused by the opening hole and is beneficial to enhance the safety reserve of the wall Ability, but increased the degree of post-wall damage, while reducing its ability to repair the structure of oblique ribs to change the way of transmission of force, making the strength of the wall tends to be uniform, the structure has better deformation recovery, and significantly reduced In the aspect of engineering design, it is suggested that the initial stiffness ratio of conversion layer should be in the range of 1.3-1.6. Because the stiffness ratio of structural conversion layer in the process of stress is more obvious, The initial stiffness of the design is higher than that of the design.The inter-story displacement and inter-story rotation of the structure are within the safety limits in each stress phase, which further shows that the structure has high anti-collapse ability and good energy dissipation performance .
